Prof. R.H. McKee (LOC)

from The Library of Congress

  • Retired at last said:
    Can anyone make out the dates on the photo? 11/2/26 doesn't fit.
  • pennylrichardsca (now at ipernity) said:
    A Ralph H. McKee was a professor of chemical engineering at Columbia University, specializing in applied organic chemistry; in 1922 he helped develop an artificial fat called "intarvin" for dietary use: www.time.com/time/magazine/article/0,9171,716396,00.html Before he landed at Columbia, he was in the research department at Tennessee Copper.
  • trialsanderrors said:
    Upper left corner: 11/6/23 and 11/5/26, both mirrored. They were likely put on file in the 1910s and used later.
  • Kristi (LOC P&P) said:
    pennylrichardsca and trialsanderrors: Thanks for the information on Mr. McKee. We will add to the record when we update!
  • John Winter said:
    He was my grandfather. I have a similar picture of him in his lab and he is older in that picture from the late 1920's/early 1930's, so the 1910 guess could be right.

Helen Miles Davis (1895-1957) and Francis Ernest Lloyd (1868-1947)

    This one would be a natural for someone to reconstruct: I assume that door and walkway are still there, all you need are two people in Washington DC, willing to pose like Mrs. Davis and Dr. Lloyd...
  • Mardi Niles said:
    F. E. Lloyd was my grandfather and my son found this photo on wikipedia. I traced it to this flicker site. Great find and terrific post! Thanks. I wonder what year it was taken?
  • Smithsonian Institution said:
    Mardi Niles Thanks for getting in touch! Always love hearing from family, and we welcome any friendly anecdotes you're willing to share in a flickr comment below. I'll definitely forward this to some of our brilliant researchers at the Archives and see if we can't get a ballpark date. Sincerely, Susannah Smithsonian Institution Archives
